fpga: Fix Spartan II FPGA booting
This patch does some minor fixing of the Xilinx Spartan II
FPGA boot code:
- Fixed call order of post configuration callback and
success message printing (result of copy-paste?)
- relocate post configuration callback only when it
is implemented
- remove obsolete comment
- minor coding style cleanup
